To ALL PERsoNs To wnoM THESE TRESEN-Ts MAY COME:

Be it known that I, Mosns H. FREEMAN, of Somerville, in the county of Middlesex, and State i' Massey," chusetts, have inventeda new and useful Self-FeedingPipefCutter; and do hereby declare the same to be fully described in the' following speciication, and represented in tlie accompanying-drawings, of which.

Figure l is a side` elevation, Figure 2 a transverse section,r'and Figure `3a horizontal section ofit. i

In such drawings, A denotes a long bar of steel, provided with a handle, B, fixed to one end of it. Along the upper' edge'of such bar, a knife, C, is fixed, such knife being arranged on the bar, and formed with its edge :inclined at and near each end,- in manner as represented in the drawings. A gallows-frame or carriage, D, .ormedvas exhibited, is applied to the bar A so as to be capable of being slid tlxereon lengthwise of the` bar, such frame or carri-age being provided with a presser, E, adapted toit so as to be capable of being moved up or down lon the side parts b 6 of the said carriage. It also has a seremF', to 4force such presser downward; and an angular notch, a, in the said presser, enables the presser to adaptitself toa pipe of any size,` when in the notch,

`and resting on the cutting-edge of the knife. Furthermore, there is a stationary stud or stop, c, extended from one siderof the bar A, and at or near the outer end of. the said barthere is anotherV such stud, d, which goes through a' hole in the bar, and is fixed to a spring, e, fastened to' the bar, and wholly arranged within a recess,

f, made in the side oflthe. bar, the wholebeing as represented in figs; 1 and 3.

` By pressing thestud d wholly within the.ba.r'A,-such stud will present no obstruction to the removal of the carriage from the bar, either/partially or wholly, but ,when the stud d projects from the side of'the bar, such stud will serve as a stop to arrest the movement of the carriage on the bar`,'the other stud also being for a similar p'nrpose.-

By having the stud crmovable, as' described, `with respect' to theQbar, we are enabled to slide the carriage partially oit' the bar, or far' enoughto admit cfa pipe being inserted within 4'the carriage, when it would be inconvenient to otherwise introduce such pipe therein. l

In order to out oil' afpipe, it is to be extended4 through the carriage, and the screw thereof is 'to be turned down,` so as tocrowd the presser against the pipe, and the latter againstone Yof the inclined parts of the knife- 4 edge; next, the whole instrument-is to be turned or revolved on the pipe, so as to 'cause the carriage vto slide on the bar, and the knife to'cut into the pipe, the effect 'produced being the same as that which would result werethe pipe rolled along the knifeedge, and at theA same time forced firmly against it, so as to cause the said edge to cut into or indent the pipe. By continuing to turn the implement on the pipe, the latter maybe cut in tvgain at the place where it is touched by the knife. A reciprocating rotary motion-of the pipe-cutter on the pipe will suiice to elect a separation of the latter. l' 'I I claim as my invention The combination of the bar A and the knife C, constructed and combined, as described, with mechanism for holding the pipe against, and rolling it on the knife, while the Alatter rnay be turned about the pipe, sub- Stantially as specified.' vI also claim the combination ofthe bar A, the knife C, the carriage D, andthe clafnp or presser E, and its :adjusting-screw F, or theequivalentgoi such presser and screw, the whole being arranged and applied together substantially asset forth.' l

I I also claim the combination of the stationary stop c and the spring-s the carriage D, the presser E,'and tsscrew F,'the wholebeing as specified.

`mtg-win.' the bar A, nl@ reif@ o,
